Need a brain booster tomorrow to wake you up from your turkey coma and help best the Black Friday crowds at the mall tomorrow? Have you considered ice cream for breakfast?

Kyorin University professor Yoshihiko Koga found that test subjects who ate ice cream for breakfast performed better on a computer-based mental-exercise drill than a control group, the Daily Mail reported Wednesday.

“Professor Koga found that ice cream eaters fired off an abundance of high-frequency Alpha-waves,” explained the Daily Mail. “These waves are linked with reduced mental irritation and high alertness.”

According to the Daily Telegraph, Mr. Koga, “is a specialist in psychophysiology, with his studies including looking into links between certain types of food and reduced stress.”

As with virtually all dietary research, however, there’s a caveat.

Mr. Koga “has yet to determine a firm connection between the mental boost delivered by ice cream and a specific ingredient,” said the Daily Telegraph, and the boost in performance may well be largely psychological, “in the sense that ice cream is a treat that triggers positive emotions and added energy.”
